Hi all, audio noobie here.

my sennheiser radio mic has been great but yesterday I was interviewing a guy in an industrial estate outside a pharmaceuticals factory and I was getting this strange fuzz going up and down in pitch. Any idea what happened?

Also, can you direct me to any posts regarding frequencies for your lav mic please? I dont want my mic interfering with police gear or a church organ etc.

Thanks.

Without hearing a sample we don't have anything to go on to come up with a diagnosis. Kind of like calling up the doctor and saying "I don't feel well, what should I do?"

The interference could be a cell phone, backberry or other personal wireless device, Have them turned off in your immediate area. Without actually hearing the noise... post a clip

Thanks guys,

I will check out that forum.
I deleted teh offending recordings off that card it seems. Theyre not in my recycle bin so I cant show them to you.
I didnt know that mobile phones, blackberries could do that.

Thanks a lot,
Brian.

Too right they will.

If you've got the pre-production time, visit the location in advance at the same time of day as the shoot and check for local radio frequency interference. Moving a few yards away may help.

Cheers.
